xbmc-pvr + tvheadend EPG info wrong
#1
Hi,

running xbmc-pvr (ppa:larsopdenkamp) on ubunutu. Often the EPG info in XBMC is wrong:
- same epg info for different channels
- epg info mixed up (wrong epg info for a channel)

Looking @ tvheadend webinterface the EPG info is OK.
After a reboot EPG info in XBMC seems to be OK.

I normally I suspend and wakeup my system with remote.

I use a script to suspend/ resume
suspend:
- stop tvheadend
- rmmod dvb-driver
- stop lirc

resume:
modprobe dvbdriver
start tvheadend
start lirc

Since a month or so xbmc reconnects to tvheadend after resume.
I disabled the xbmc database regarding EPG, this does not seem to work.
When I try to reset the database XBMC crashes and I have to restart xbmc.

any help is appreciated....

please pastebin a full debug log. I've noticed an occasional error in the epg data here too, so it's probably either a bug in tvheadend, the add-on or xbmc's epg code.

xbmc-pvr [Eden-PVR builds] [now included in mainline XBMC, so no more source link here :)]

Found a problem with PVR? Report it on Trac, under "PVR - core components". Please attach the full debug log.

Hi,

Enabled debug log in xbmc. It happend after I had to reboot because xbmc hanged at some point when switching to another channel... so i am not sure this particular case will help in finding the problem.... I had enabled the epg database in xbmc a few hrs before. Xbmc displayed 4 or 5 times the same epg info on different channels. Checked epginfo comming from tvheadend via webinterface of tvheadend this seemed OK.

I am also seeing the same behaviour. Wrong EPG data for a channel, and duplicate EPG data for multiple channels.

Hi,

I think the problem lies in repeated suspend/resume. The problem occurs when resumed from sleep after considerable amount of time has past (ie next evening)
(not sure but it looks like double epg info and mixup = EPG info of channels watched previous evening)

Other test I did:

When I run XBMC on my laptop everything is fine (upon startup EPG info is updated)
so i am looking @ TV (just resumed from standby): everything is double/mixed up
looking @ my laptop : everthing OK (EPG just updated)

possible solution: update EPG on reconnect to tvheadend

dunno how to do this but I realy think it solves the problem.

note: I start XBMC on ubuntu after normal login (gnome) and use remote to suspend/resume
no XBMC-live

I don't think suspend/resume is the cause. I don't use suspend/resume. My XBMC and Tvheadend machine (same machine) is on 24/7. I also tried playing a channel the other night, and when the stream started playing I thought the EPG was wrong again. However, I went into Videos and played the same channel via the HTSP stream I had added as a video source, and that was a different show (what was reported by the EPG). I think the Live TV section played the wrong channel. I didn't test or try to reproduce this issue.

I see the same issues on both my boxes, guide data is either totally wrong or the first few get duplicated throughout the channel list - EPG is normally fine once XBMC is restarted.

Another oddity I've noticed is that in timeline view if a channel has no EPG data the channel isn't displayed at all in the EPG grid - I'd expect to see it and just have it show 'no guide data' or similar like the TV Channels list does.

How did you get the EPG to load in tvheadend? I'm in North America so I used the tv_grab_na_dd script for schedulesdirect but my EPG never injects any new events.
